Well for those of us who applied to Oregon State, it was the virtual mailbox that we were, uh.. clicking? My email program checks for new email every minute, and before I finally got my denial email, every time there was new email I'd just get all excited and hope that it was a decision letter! The fact that I subscribe to a number of forums didn't help, so I was experiencing this a lot of times throughout the day while I was at my computer.
